VCP 1 Documentation›Essentials
Release Notes
Every version of the VClarity Protocol, what changed in each, and where its documentation lives.
The protocol evolves additively within a major version — a v1 integration keeps working against every v1 gateway — and each documentation set stays available after it's superseded, so you can always read the exact spec you built against. How consumers negotiate versions at runtime is covered inversion negotiation.
